@348f4b7b Max Boot in WaPo has some stark numbers: https://www.washingtonpost.com/opinions/2023/10/02/ukraine-aid-great-investment/

At the cost of 0.65% of the total US military budget and 0 (zero) US troops on the ground, #Ukraine severely crippled Russia's ability to wage war – Russia's, America's strongest adversary's for over half a century.

Furthermore, that same 0.65% is also holding China back from invading Taiwan.

For comparison, U.S. spent $8 trillion on Afghanistan and Iraq, where 7,000 Americans were killed and 50,000 were wounded.
